【摘要】 为建立大安山矿冲击地压危险性与井田地应力场之间的内在联系,结合大安山矿地应力测量结果,全面分析了大安山矿地应力场的类型、作用特征及其与区域构造的关系.分析大寒岭倒转向背斜的形迹、剖面特征及其对井田地应力场的影响,采用数值模拟方法对研究结果进行验证.研究表明:水平构造应力在大安山井田应力场中起控制作用,井田应力场为典型的构造应力场,井田内最大主应力为NW-SE向.大寒岭倒转向斜发育的次级褶皱——百草台倒转向斜轴部区域应力集中,为向斜南翼的2~3倍.大安山矿处于极高应力状态,具备发生冲击地压的构造应力条件.更多还原

【Abstract】 In order to establish the inner relationship between rock burst hazard and stress field in Daanshan coal mine,this paper utilized the stress measurement results to analyze the types and features of stress field and its relationship with regional tectonic,analyzed the appearance and profile characteristics of Da Hanling exocline and its effect on stress field,and validated the results by using the numerical simulation method.The research results show that the horizontal tectonic stress plays a control role in Da’anshan stress field.The stress field is typical tectonic stress field and the maximum principal stress is NW-SE.Da Hanling inverted syncline grows secondary folds——Bai Caotai inverted syncline is a stress concentration region,its stress is 2~ 3 times of South Syncline.Daanshan coal mine is in very high stress state,and it has the tectonic stress condition for rock burst.更多还原
